What is Systemic injection and how does it work?
Systemic injection is a type of trunk injection where small amounts of
therapeutic chemicals, contained in sealed capsules, are introduced
into shallow trunk wounds around the base of a tree. The injected
chemicals are then distributed systemically by sap movement within
the tree to the branches, leaves, and even roots within a few hours
after injection. The chemicals, such as antibiotics, fungicides,
insecticides, and mineral nutrients, are added directly into a tree
without any contact with the environment.
